This' invention relates to railway cars in gen1 eral and in particular to railway'cars of .thearticulated type wherein adiacenti car bodies rest upon a. common supporting' truck; In the past ears of the articulated type have been builtl with ,3,

the adjacent car bodies either supported on a common truck bolster with theY side' sway taken care: of by side bearings', or the cars have been supported upon independent holsters carried by a common truckv with the bodies again stabilized by.' use of truckl sidev bearings.. It is obvious that when, for any reason due to' eccentrici'ty of load or when the cars are rounding a curve, the' body contacts the side bearingsr road shocks" Will be transmitted directly into the car body also obvious that extremely limited movement between the body and truck 'is permissible" thevold type of side bearnfrg arrangementJ and su'clt limited movement neeessariiylniakes a hard riding car. It is an obiect, therefore, of the' present invention tof provide articulated cars" in which 'adjacent ends of adjacent ears mutualiy interact to stabilize side sway of the cars without using truck side bearings. l'

It is another object of the invention to provide adjacent ends of adjacent carsfo' the' articulated type with 'means' tol resilietly stabilize' side sway between the: cars and' independenty of any bearing' on the truck except at the center. v

Another objecti of Vthe' invention' is vthe provie sion of articulatedcars which'. checar' ofthe adjacent units? is provided withi a depending elon-v gated center bearnig engaging within a' 'deep truck bolster in order that the Vs'id'ev sway of th car may be directly controlled b'y the bolster'.

A still further object of th'e' invention' i's the provision of a new and improved end casting for usewitharticulated cars.

yThese and other obzec'tsI 'of the'invention `will be' app'azrent to persons skilled inthe art from a study of the following deseriptidnand' accom-e pa'nyin'g drawingsT in which:

Referring now tothe; drawings in detailv and particularlyFigi-ire 6, itwi'l'l beseen that theetire-unit is made liipof endcars A and one: or

Lii'ore 'ceri'tercars'Bl `lrithe' instance shown the end cars A are supported'upon independent trucks C, while the adjacent ends'of cars Av and B' are 'supported upon common trucks D. With this arrangement' it will -be noted that the number of trucks required will always exceed the nurri-v ber of cars by one. Merely for illustrative purp'ses, the c'ar B has been provided'wth depend` ing' elongated center bearings, later to be' described', which will support th'islcar directly upon thetrucks- D'With the ends/'of cars A resting upon the upper portion of the center'beiri'ng.:

Referring now't'o IEigs'.,A 1' to= 5' inclusive; it will be seen that the cars are of the side carrying type .having'side'sillsA 2 connected' together at their ends byicbnlbined e'n'd structures" aiid body-'bol'- s'ters. These end structures orb'ody bol'sters are the instance' shown; aniner` transverse member 4 of' channel section connects the side' sills and caps the `eh'ds of oor stringersi E' adapted to support the oor (not shown). 'Ihe side *sills project outwardly beyond this .tra sverse member and arecapp'edby'mean's- 'of' a rearwardly directed channel' member' 8 adapted to overlap anclb'e' rigidly secured Vto* oppositely directed wings |'0'-'of a combined end an'd'cent'r bearing casting. 'I'he Wings l0 are preferably of channel section and have the upper I'angelZ thereof merging intoia bracing-gusset M which is' continuous with al top plate I6 overlapping ari-df formed: integral' with center webs I8. Each of these/webs is provided` with an' outwardlyturned' foot or 'harige 2 U braced by gussetsll preferably located int the saine plane asf th'e beforementioned gussets |4` and plate I'G The foot or flange portion 2o" and 'wings ofthe casting are' adapted Ato 4be rigidly secured toY the transversez member' 4' and endi channel 8' respectively by' any" suitable 'm'eafrfssuch as;4v rivets 2 3. `arid transverse member' 4' are' additional'ly'joinedtogether and stifen'ed' by "botto'zfri'V plate' 26 and by' side panshaped bracings 28, the latter i r pairs 'on 'either sidof the'center line of' thefend structure' and' in the' region 're the' stabilizing means wilt be attached. channel 'section' wings are' more" or lessi continuous completely across the'casth th'us" providirlga webportion 3o at the center lofthe cajstifng joining the-'cen- IE previ'slyrei'erred to'.

extension downwardly to merge into a bowl-like member 34 which will thus be braced by these extensions and also by a curved rib 35 formed integral with the web 30 and in turn additionally braced by means of inclined wall38 extending between the bowl-like portion and the main body of the casting. The walls of the bowl-like mem-k ber 34 are deflected inwardly and downwardly as at 40 merging into an elongated depending hollow portion 42 suitably braced internally-.by

ribs 43 and provided adjacent its upper and lower ends with trued surfaces providing areas for reception of bearings 44' and 46 respectively. These bearings are adapted to support and guide the elongated projection in Yan elongated opening in the truck bolster 53, which in turn will be provided with cooperating bearingzareas 52 and 54 respectively. The lower Vend of the elongated projection is provided with a shoulder 55 adapted to receive a plate 51`by means of which a bolt 58 and cup 59 may function toV lock the projection in the truck bolster and prevent /its being lifted therefrom. The walls of the elongated projection are projected upwardly through the base 65 of the bowl-like portion, thus providing a shoulder 62 which will act as a centeringV control for the bearing formed on the cooperating casting carried by car A. Y

The casting carried, in the instance shown, by car'A also has. a continuation of the bracing center webs extending as at66 and merging into a' curved wall B8, which wall is extended and provided at itsV lower edge with bearing area 10 adapted to rest upon the base of the bowl-like member previously referred to. This 'bearing area is reinforced by an inner annular wall 12' and bracing gussets 14, some of which are extended upwardly to engage the end bracing web 30. Flanges 16 are formed on the curved wall 68 and adapted to overlap the bowl-like member, permitting the use of any suitable type of sealing means (not shown) for retaining grease in the bearing and for excluding foreign matter. The forward edge of the curved wall 68 is vformed also with a curved projection 18 adaptedV to come into close contact with a thickened area 80 formed on wall 36 of the casting carried by car B, thus forming a bufiing area' adapted to transmit buffing strains from one casting to the other independently of the bearing area. It will thus be seen that the castings carried by cars A and B are provided with center bearing structures, permitting the movement of one casting relative to the other, such movement consisting of rotational movement in a horizontal plane and a slight rocking due to the limited clearances between the bearing areas ofthe casting carried by car A and the bearingareas of the casting carried by car B. v In order to stabilizeand control any rocking movements of the car bodies, shoe members 84 are riveted or otherwise secured to the end channels and casting wings between the bracing pans 28. Each of these shoes is provided with a bearing pad 85-adapted to slidably bear upon an upper leaf 85 of a cantilever spring, the anchored end of which is carried by a bracket 88 bolted or otherwise secured to the end channel and wing of the casting carried by car B. As clearly shown in Figs. 3, 4 and 5 the bracket is formed with a pocket adapted to receive the spring which will be held in the pocket by means of anchor plate 89 and bolts 90. The cantilever springs are locked in position in the pocket by means of ledges 92 formed on the plate 89 and adapted to engage within notches 94 in the base end of the spring leaves. In this manner any broken springs may be readily replaced by merely loosening the bolts, removing anchor plate 89 and withdrawing the desired spring leaf.

It will be obvious that due to the elongated projection of the casting carried by car B into the opening in the truck bolster, the car B and bolster must'rock and move substantially in unison in all directions except for rotational movement in a horizontal plane, thus by controlling the sway of the truck bolster in any well known manner, the sway of car-B is controlled. By pro- Viding the stabilizing springswhich will be contacted by the stabilizing pads of car A, any rocking movements of car A are transmitted resiliently to car B and absorbed finally by the truck bolster through the elongated depending projection. It will be obvious thatslight swaying of the cars A or B will be absorbed by cars B or A respectivelydue to the mass of the structures without such sway being transmitted to the truck through the bolsters. In this manner an eX- tremely easy riding arrangement has been provided which is also extremely flexible due tothe articulated connections. While theinvention has been described more or less indeta'il, it-is 'obvious that various modifications and arrangements of parts will be apparent to persons skilled in the art from a study of the preceding description and all such modifications and rearrangements of parts are contemplated as' will fall within the scope of the following claims.
